Mortality and serious injury of northern right whales (Eubalaena glacialis) in the western North Atlantic Ocean
Northern right whales in the western North Atlantic number about 300 animals and have shown little sign of recovery in recent decades. Mortality and serious injury due to human activities, particularly commercial fishing and shipping, are thought to be significant factors limiting their recovery. From 1970-1999, 45 right whale deaths were reliably documented. Sixteen of these fatalities (35.5%)...
متن کاملEstimated calf and perinatal mortality in western North Atlantic right whales (Eubalaena glacialis)
Reduced reproductive success has contributed to lack of recovery of the endangered western North Atlantic right whale (Eubalaena glacialis). Here we examined the specific life history period from just before birth through the first year to estimate calf and perinatal losses between 1989 and 2003. The lower bound estimate (17 mortalities from 208 calving events) included documented calf mortalit...
متن کاملAnalysis of fecal glucocorticoids in the North Atlantic right whale (Eubalaena glacialis).
Very little is known about the endocrinology of the baleen whales. The highly endangered North Atlantic right whale (NARW; Eubalaena glacialis) is a good model species, because most NARW individuals are photo-identified with known histories. We used an 125I corticosterone assay, shown to reliably measure cortisol metabolites, to determine glucocorticoid metabolite concentrations in 177 NARW fec...
متن کاملExpert elicitation of seasonal abundance of North Atlantic right whales Eubalaena glacialis in the mid-Atlantic
North Atlantic right whales Eubalaena glacialis are among the most endangered of the large whales. Although protected since 1935, their abundance has remained low. Right whales occupy the Atlantic Ocean from southern Greenland and the Gulf of St. Lawrence south to Florida. The highly industrialized mid-Atlantic region is part of the right whales’ migratory corridor, and gaps in knowledge of the...
متن کاملCalls of North Atlantic right whales Eubalaena glacialis contain information on individual identity and age class
Passive acoustic monitoring is a powerful tool that allows remote detection of marine mammals through their vocalizations. While call detection provides information on species presence, additional information may be contained within the vocalizations that could provide more information regarding the demographics and/or number of individuals in a particular area based on passive acoustic detecti...
